Is it safe to remove car fuses?

What is fuse and what is its purpose What will happen if no fuse is provided n the electric circuit?

The fuse is an electrical device that breaks the circuit if the over current (more than the allowed limit) passes through it. It is made of thin tin copper wire plate, so it has a low melting point, making it easier to break the circuit.

What will happen to a fuse if there is an overflow of electricity?

If a short circuit occurs—or even if too many appliances get hooked up to one wire so that too much current flows—the wire in the fuse heats up quickly and melts, breaking the circuit and preventing a fire from starting.
